CAM Optimization
When you enable the CAM optimization, if a Policy Map containing classication rules (ACL and/or DSCP/ ip-precedence rules) is applied
to more than one physical interface on the same port-pipe, only a single copy of the policy is written (only one FP entry is used). When you
disable this command, the system behaves as described in this chapter.
